Is it possible. Mine is only partially working but still has good spring pressure. I'm sure with a good cleaning of the contacts it would work fine. However I can't seem to get the thing apart easily. The back cover when unlocked at the 4 tabs still won't lift off.
Anyone help as I don't think you can buy them new anymore.

Hi, had the same issue. I dowsed mine with WD40 Spray and made sure it got inside. Then blew it out with canned air and let it sit and drain into a paper towel for a couple of days, cleaned off the outside with rubbing alcohol and installed it. Been working good for the last couple of years

Good Luck - Hope this helps.

IIRC, when I did mine I found that there was a metal ring that held the "rocking" part of the switch to the body. Seems like I had to remove that metal ring ( carefully) to get things apart. I used RadioShack electronics cleaner, but also used emory cloth to clean the underside of the contacts. There was a lot of corrosion.

Found this thread and used the outputs to test the switch before I buttoned things back up.

Interesting link but it seems to be missing one step. On mine the rocking, spring loaded button extends through the circuit board by a center post. It is held there by a spring and a washer and the end of the post appears to have been heated flat by the factory to hold it all together. How do you service that?? It has to come apart to remove the circuit board!
On mine this washer broke as I poked at it so everything came apart. I will hope to re-assemble everything and hold it together with a horseshoe clip from a carb kit.

I remember now that I used a dremel to lightly trim the post where it was melted so I could remove it. When I replaced it, I think I found a nut that would thread itself onto the post. It was just a regular nut- nothing special. The post was soft enough that it cut it's own threads. I'm sure I used a dab of Red Locktight on it just to be safe. I'm sure one of those push on type retainers would work too, if you can find one the right size. Or you could always just slide a washer on there, and then heat melt the post with a soldering iron.

Ive just sprayed tv tuner cleaner into dirty switches to make them work again. It wont short anything out, so it dont matter how soaked it gets. Takes grime and carbon off the contacts.

Fixed mine. The retaining washer had broken on my post so everything came apart. After cleaning all the contacts I re-assembled everything and held the spring down while I slipped a horseshoe clip around the post. I dropped a very small amount of epoxy glue on top of that and now everything is working fine.
